Satoshi's topic also sadly not the highest either 
I think you are getting quite emotional here. I have respect for the man and I believe everyone does so. That doesn't mean this thread need to achieve the most merits. Yes, this thread must have a place on the history of cryptocurrency forever but it has less to do with the merit if you consider merit as theymos defined. I encourage people to give merit to posts that are objectively high-quality, not just posts that you agree with.
He did build bitcoin core and the forum for which now bitcoin is mosty discussed. If that's not a high quality thing to do then what are we doing here (that thread is the first thread on here that has a link to the software satoshi made - assuming satoshi is the collective name for a group of people as I see it to be - the whitepaper references a 'we').
I don't think I ever gave the wall observer thread enough of a look into before now also so maybe I shall try that (I think it was filled competely with spam at one point so it was pretty useless but it does have it's own moderator now so)...
